Measure and transfer precise angles with rotating 12-inch arms
Rotating arms lock into precise angles for direct measurement rather than estimation. This goniometer's seven-inch legs extend the full twelve inches when opened, providing enough reach to measure angles in larger drawings, pattern pieces, or dimensional layouts where standard protractors fall short. The central pivot maintains smooth rotation through 360 degrees while keeping measurements stable once you've positioned the arms.
Both inch and metric scales run along each leg, eliminating the need to switch between measuring tools when working from different reference systems. The compact 1¾-inch body houses clear degree markings that remain legible even when measuring acute angles. Whether you're checking perspective convergence in architectural drawings, verifying pattern angles in design work, or measuring joint angles for figure studies, the tool stays in position while you record measurements.
The rotating mechanism handles repeated adjustments without loosening, maintaining accuracy across multiple readings. Drafters and technical illustrators keep this goniometer within reach for the kind of precise angle work that separates professional results from approximations.
